OK guys!!! "Let The Modding Begin" with A.R. Headers' direct bolt-in S/S long tube header systems. Based on the LX platform header design, our Challenger systems were tweaked for additional clearance and better fit. All traditional ARH features come standard including 3/8" thick flanges with hand ported inlets, U.S. made 304 S/S throughout, merge collectors with scavenger spikes, 200 cell metallic substrate cats, and your choice of 1-3/4"or 1-7/8" primary headers. Expect outstanding performance gains throughout the rpm range. For peak performance we recommend street and/or dyno tuning.
